  • open graphics library — (graphics, library)   (OpenGL) A multi-platform software interface to graphics hardware, supporting rendering and imaging operations. The OpenGL interface was developed by Silicon Graphics, who license it to other vendors.

Many operations require a frame buffer. OpenGL is network-transparent, and a common extension to the X Window System allows an OpenGL client to communicate across a network with a different vendor's OpenGL server. OpenGL is based on Silicon Graphics' proprietary IRIS GL.
  • operational semantics — (theory)   A set of rules specifying how the state of an actual or hypothetical computer changes while executing a program.
